"Ausgehend von Industrien mit hohen Fixkosten und vernachlässigbaren Grenzkosten (z.B. Film- und Fernsehindustrie, Softwareindustrie, Pharmazeutische Industrie) wird untersucht wie sich überregionale Zusammenschlüsse zwischen 'downstream distributors' (z.B. Kinos, Kabelbetreiber, Einzelhändler, Krankenhäuser bzw. Krankenkassen) auf die Angebotsvielfalt auswirken. Aus verhandlungstheoretischer Sicht werden dazu in diesem Beitrag die Auswirkungen von überregionalen Zusammenschlüssen zwischen lokalen 'downstream distributors' auf den Eintritt von Inputpoduzenten untersucht. Es wird gezeigt wie überregionale Zusammenschlüsse von 'distributors' deren Verhandlungsmacht gegenüber Inputproduzenten erhöhen können und damit die Anreize zum Eintritt in die Inputindustrie verringern können. Hierzu verwendet dieser Beitrag eine verallgemeinerte Nash-Verhandlungslösung, um die Preisbildung auf dem Inputmarkt zu analysieren." (Autorenreferat)

One of the most frequent criticisms of the Illyrian model of the labour‐managed firm is that it does not take into account key institutional factors which are likely in practice to eliminate the perverse short‐run supply and degeneration results well known in the literature. This paper presents a new model of the labour‐managed firm, incorporating several of the most significant institutional factors actually in evidence in Western cooperative sectors. The free‐entry producer cooperative model includes differing member and nonmember compensation methods, free access to membership, and special capital financing and shutdown rules. The new model's results differ from Ward's Illyrian firm model in a number of ways: first, capital is always variable for these firms, so the perverse short‐run supply response does not apply; second, free‐entry producer cooperatives do not degenerate into capitalist firms as Illyrian firms do; and third, such cooperatives will always have higher survival rates than both Illyrian and conventional firms.

Forthcoming, Journal of Political Economy ; International audience ; This paper builds a framework for the analysis of macroeconomic fluctuations that incorporates the endogenous determination of the number of producers and products over the business cycle. Economic expansions induce higher entry rates by prospective entrants subject to irreversible investment costs. The sluggish response of the number of producers (due to sunk entry costs and a time-to-build lag) generates a new and potentially important endogenous propagation mechanism for real business cycle models. The return to investment (corresponding to the creation of new productive units) determines household saving decisions, producer entry, and the allocation of labor across sectors. The model performs at least as well as the benchmark real business cycle model with respect to the implied second-moment properties of key macroeconomic aggregates. In addition, our framework jointly predicts procyclical product variety and procyclical profits even for preference specifications that imply countercyclical markups. When we include physical capital, the model can simultaneously reproduce most of the variance of GDP, hours worked, and total investment found in the data.

"We show that deviations from long-run stability of product prices are optimal in the presence of endogenous producer entry and product variety in a sticky-price model with monopolistic competition in which price stability would be optimal in the absence of entry. Specifically, a long-run positive (negative) rate of inflation is optimal when the benefit of variety to consumers falls short of (exceeds) the market incentives for creating that variety under flexible prices, governed by the desired markup. Plausible preference specifications and parameter values justify a long-run inflation rate of two percent or higher. Price indexation implies even larger deviations from long-run price stability. However, price stability (around this non-zero trend) is close to optimal in the short run, even in the presence of time-varying flexible-price markups that distort the allocation of resources across time and states. The central bank uses its leverage over real activity in the long run, but not in the short run. Our results point to the need for continued empirical research on the determinants of markups and investigation of the benefit of product variety to consumers"--National Bureau of Economic Research web site

This paper studies the role of endogenous producer entry and product creation for monetary policy analysis and business cycle dynamics in a general equilibrium model with imperfect price adjustment. Optimal monetary policy stabilizes product prices, but lets the consumer price index vary to accommodate changes in the number of available products. The free entry condition links the price of equity (the value of products) with marginal cost and markups, and hence with inflation dynamics. No-arbitrage between bonds and equity links the expected return on shares, and thus the financing of product creation, with the return on bonds, affected by monetary policy via interest rate setting. This new channel of monetary policy transmission through asset prices restores the Taylor Principle in the presence of capital accumulation (in the form of new production lines) and forward-looking interest rate setting, unlike in models with traditional physical capital. We also study the implications of endogenous variety for the New Keynesian Phillips curve and business cycle dynamics more generally, and we document the effects of technology, deregulation, and monetary policy shocks, as well as the second moment properties of our model, by means of numerical examples.

Entrepreneurs who decide to start a business are faced with different levels of effective entry costs in different countries. These costs are heavily influenced by economic policy through entry regulation and subsidies. In this paper we present a two-country general equilibrium model with monopolistic competition and heterogeneous firms where entrants pay a sunk cost and randomly draw their productivity level. Governments collect lump-sum taxes and subsidize these sunk entry costs for the domestic entrepreneurs. One motive for this policy, valid already in autarky, is to tighten market selection. This selection effect leads to better firms that produce and sell more output at lower prices. In the open economy there is another, strategic motive for entry subsidies as the tightening of market selection leads to a competitive advantage for domestic producers in international trade. Our analysis shows that entry subsidies in the Nash-equilibrium are first increasing, then decreasing in the level of trade freeness. This implies a U-shaped relationship between trade freeness and effective entry costs. Comparing the non-cooperative and the cooperative policies, we furthermore show that there is first too much and then too little entry subsidization in the course of trade integration.

Abstract
In a homogeneous good, Cournot duopoly model, entry may occur even when the potential entrant has no cost advantage and no independent access to distribution. By sinking its costs of production before negotiating with the incumbents, the entrant creates an externality that induces the incumbents to bid more aggressively for the distribution rights to its output. Each incumbent is willing to pay up to the incremental profit earned from the additional output plus the incremental loss avoided by keeping the output away from its rival. This implies that the incumbents are willing to pay up to the market price for each unit of available output. A sequential game in which the incumbents produce first is analyzed, and the conditions under which entry is deterred by incumbents' preemptive capacity expansions are derived.

In this paper the authors review recent research on the characteristics and operations of service multinationals. To provide an understanding of the determinants of internationalization, entry modes, and strategies of product and market diversification, examples are taken from producer service firms with specific emphasis upon accounting and advertising services. The competitive advantage of service multinationals in the United States and Western Europe is at the core of most discussion; however, the competitive strategies of the Japanese advertising firms vis-à-vis their Western counterparts are discussed to highlight interorganizational differences. This paper is organized into five sections: the definition of services and the determinants of growth in producer services in the industrially advanced nations; theoretical explanations of international investments in services; empirical research on the determinants of internationalization, entry mode, and business strategies of service firms; industry-specific examples of competitiveness in accounting and advertising; and implications for future research.
